The graindensity of core samples is calculated from the measured dry weight divided by the grain volume.
用干燥岩心样品重量除以颗粒体积得到岩心样品的颗粒密度。

Significant negative associations existed between grain width, thickness and graindensity, which could be associated with grain quality.
粒重与其他籽粒性状均呈显著正相关,而涉及籽粒品质的容重与粒宽、粒厚呈显著负相关。

Based on the compaction model of sandstone mudstone alternating beds, we advance a new formula for formation graindensity, which conforms to grain volume and mass balance law.
